CHT AS1701 RTV, silicone adhesive sealant
Categories:	Polymer; Thermoset; Silicone; Silicone, RTV, Adhesive/Sealant Grade
Material Notes:	Description: This is a non-corrosive, neutral cure, 1-part, RTV (Room Temperature Vulcanizing) silicone adhesive sealant. It is one in a range of Alkoxy cure products which are solvent free. It exhibits excellent primerless adhesion to many substrates and cures at room temperature when in contact with atmospheric moisture to form a tough rubber. This product will not corrode copper or its alloys and is suitable for use with electronic components. Key Features Non corrosive Excellent adhesion to most substrates Fast skinning Non slumping paste Application: Vibration damping and board coating e.g. voltage regulators Cured Product: 7 days at 23+/-2°C and 50+/-5% humidity Information provided by CHT Group
